define AVR_HELP

 AVR extras:

   debug    : compile with minimal optimization and debug symbols
   debugopt : compile with debug symbols
   xnp      : compile for network programming

 Programmer options:

   dapa         : (default) use parallel port programmer
   mib510,<dev> : use MIB510/MIB520 serial port programming board at port <dev>
   eprb,<host>	: use EPRB at hostname <host>
   avrisp,<dev> : use AVRISP serial programmer at port <dev>

   The dev or host parameter for the programmer option need not be specified,
   in which case it is expected to be defined as in an environment variable of
   the same name in all caps (such as MIB510, EPRB, or AVRISP).
